UPDATE 3: Contrary to previous reports, a “source connected to the singer” claims to TMZ that Lovato did not overdose on heroin, but declined to name the specific opioid.

UPDATE 2: A representative for Lovato shared a statement with Variety saying, “Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support. Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now.”

UPDATE: Demi Lovato’s next concert set for Thursday at Atlantic City Beach in New Jersey has been canceled. “Demi’s Atlantic City appearance on July 26th has been canceled in light of today’s news,” a rep for Live Nation said in a statement. “Tickets will be valid to attend the Lauv performance on July 26th along with The Chainsmokers show on July 29th as part of the Atlantic City BeachFest Concert Series. Refunds are also available at point of purchase if preferred.”

Lovato’s episode of the Fox gameshow “Beat Shazam” that was previously taped and scheduled to air tonight was also canceled. “In light of recent reports, we have decided to replace the episode of BEAT SHAZAM with another all-new episode,” the network said in a statement per Yahoo. “Our thoughts go out to Demi and her family.”

Demi Lovato was hospitalized Tuesday morning for an alleged overdose, according to TMZ. Lovato is in “stable” condition, an unnamed source tells Variety.

A spokesperson for the Los Angeles Fire Department confirmed to Rolling Stone that it responded to a medical emergency call at 11:22 a.m. from a Hollywood Hills residence in the 8000 block of Laurel View Drive, where Lovato lives. The LAFD transported a 25-year-old female patient to a local hospital.

The Los Angeles Police Department confirmed that a police vehicle was also dispatched after the emergency call, but there was no criminal activity at the location.

Per NBC, the first responders who arrived at Lovato’s home used naloxone, which counteracts the effects of an opioid overdose.

Lovato’s representatives did not respond to Rolling Stone‘s request for comment.

The “Sorry Not Sorry” singer has been transparent about her struggles with eating disorders and alcohol and cocaine addictions. Last October, those battles were the focus of an intimate documentary, Simply Complicated.

At the time, Lovato spoke to Rolling Stone about being honest with her fans and living with bipolar disorder. “If anything, I’m proud to be bipolar and speak about it. Bipolar is a mood disorder. I deal with mood swings, I deal with episodes of mania, and bipolar-depression phases as well. But I’ve used my voice to help others, and I feel proud that I’ve been able to do that.”

In March, Lovato announced on Twitter that she was officially sober for six years. “So grateful for another year of joy, health and happiness,” she wrote. “It IS possible.”

Just months later, in June, she released the heartfelt ballad, “Sober,” about a person who suffers a relapse. Lovato became emotional performing the song for the first time live during Rock in Rio. The lyrics, in part, read as an apology to disappointed fans: “And I’m sorry for the fans I lost/ Who watched me fall again/ I wanna be a role model/ But I’m only human.”
